Give an example of body characteristics used to determine how close tow species are in term of evolution and explain it .

Explanation

**Step-by-Step Solution:**

1. **Understanding Evolutionary Relationships:**
To determine how close two species are in terms of evolution, scientists study various body characteristics. One of the primary characteristics used is the presence of homologous organs.

2. **Definition of Homologous Organs:**
Homologous organs are those that have a similar structure but serve different functions in different species. This similarity in structure suggests that these species share a common ancestor.
